This discourse was taught by the Blessed One, taught by the Arahant, the fully enlightened Supreme Buddha. This is as I heard:
“Monks, a monk endowed with two things, lives with happiness and joy and has aroused energy for the destruction of taints. What are the two? Being moved by a sense of urgency at times for urgency and, being moved, making effort wisely, for the realization of the truth. Monks, a monk endowed with these two things lives with happiness and joy and has aroused energy for the destruction of taints.”
This is the meaning of what the Blessed One said. So, with regard to this, it was said:
The insightful and ardent monk investigates the true nature of life; this monk is moved by a sense of urgency at times for urgency.
In this way, living ardently with peaceful behaviour, tranquilizing the mind through calming meditation, the monk with a stilled mind attains the destruction of suffering.
This, too, is the meaning of what was said by the Blessed One. This is exactly as I heard.
